MRI Birdcage Coil

Application ID: 16991

Magnetic resonance imaging (MRI) systems generate a magnetic flux density (B-field) to create images. Providing a homogeneous field distribution within a birdcage coil is a key factor for improving the quality of the scanned data.

A homogeneous magnetic field can be found through quadrature excitation, in combination with the appropriate number of lumped elements.

In this model, the magnetic field is optimized by parameterizing the value of capacitors and maximizing the circular polarity of B-field, around both a human head and an air phantom.

This model example illustrates applications of this type that would nominally be built using the following products:
